Hinduism sets down Rules for every one.
It does not say that Hindus alone should follow these rules.
Nor does it sat that only those who follow these Rules are Hindus.
These are suggested ways o Life as found by wise men.
We have these sets of Rules, not classified as rules as such in the Vedas, Puarana, Epics Like the Mahabharata and other literature .
So it becomes difficult to codify all these under one head.
But efforts have been made earlier with various Smritis, like Manu Smriti,Sukra Neethi,Vashista Needhi,Vidhura Needhi.
Even these texts are too long and at times difficult to understand.
Sree Vatsa Somadeva Sarma,under the guidance of Kanchi Maha Periyavar, published a book in Tamil,’Vaidika Samvardini’,containing the essentials of behavior according to Hinduism.
These rules, contrary to popular misconception, is to be followed by all, not meant for only Brahmins.
